I don't see that LokiD's speculation is any different or worse than anyone else's. Plenty of people have insisted that their theories were absolutely true, only to be disproved later. A couple of people pushed the Szostak-as-Janet theory really hard, but now that we know she isn't playing that character all is forgotten. Pepper's gonna die, Stark is going to space in his Deep Space armor, Mandarin is Killian's lackey, etc., all speculation we've had in this thread (some of which I agreed with) and all virtually certain to be wrong. Was anyone hurt by that spec? I doubt it.
